AARO case resolution: "Go Fast" (2025)
AARO's official resolution of the "Go Fast" video, one of the three Navy videos the Department of Defense released in 2020. Modelling the aircraft's and the object's geometry for every possible wind direction, AARO finds that the apparent high speed low over the water is a parallax effect. The object was at about 13,000 feet, drifting at or near wind speed, and showed no anomalous performance. It does not identify the object. NASA's 2023 study reached a similar result.

Facts and claims
- documented AARO's case resolution of 6 February 2025 on the January 2015 Navy F/A-18F FLIR video states: "AARO cannot definitively identify the object, but it displayed no anomalous performance characteristics." It assesses with high confidence that the object did not move at anomalous speeds. Source: doc-aaro-gofast.pdf
- documented AARO puts the object at about 13,000 feet, not near the ocean's surface as it appears, moving at about 72–161 mph relative to the ground depending on heading, or about 5–92 mph once the 69 mph westerly wind at that altitude is compensated for. It did not move against the wind in any simulation. Source: doc-aaro-gofast.pdf

Claims
- The objects Navy F/A-18 crews tracked off the U.S. East Coast in 2014–15 were not conventional aircraft, drones or balloons (evidence against claim) — AARO: with high confidence the GoFast object “did not move at anomalous speeds”

- Jon T. Kosloski (presented by) — He presented AARO's resolution of the GoFast video, publishing its calculations
- Ryan Graves (disputes) — AARO assesses “with high confidence” that GoFast did not move at anomalous speeds
- Tim Gallaudet (partly accepted by) — He concedes AARO's point that GoFast was not fast (“I don't dispute that”) but disputes its wider conclusions
